(KTLA) — Over 100 people were arrested during a massive drug bust operation in Southern California.

The multi-day effort, called “Operation Street Sweeper,” stemmed from “increased criminal activity and complaints from community members and businesses,” police said.

Over a three-week period, 46 people were seen buying a variety of illegal narcotics including methamphetamine, fentanyl, cocaine, PCP and Psilocybin mushrooms. 

In a three-day operation, 44 drug dealers were identified and 33 of them were arrested for narcotics sales violations. 

With help from nearby agencies, 71 additional suspects were also arrested for multiple charges including:

• 32 misdemeanor arrests were made for trespassing, public intoxication, possession of drug paraphernalia, and illegal possession of controlled substances
• 21 outstanding misdemeanor arrest warrants for shoplifting, petty theft, trespassing, possession of drug paraphernalia, illegal possession of controlled substances, and being under the influence of a controlled substance
• 15 arrests for violation of parole, probation, and post-release community supervision
• 3 outstanding felony arrest warrants
• 3 probation searches were conducted at local motel rooms
• 2 search warrants were served at local residences

A total of 104 people were arrested during the large-scale bust. Most of the people arrested claimed to be homeless or living in various motels in the area, officers said.

During a probation search of a motel room, police discovered a woman who was wanted for a 2022 felony drunk-driving crash that critically injured two women and a 4-year-old boy.

Inside her motel room was also a man with an outstanding warrant for burglary. Police discovered the man possessed several thousand dollars worth of stolen merchandise as well.

Since the arrests, medical aid and police calls for incidents along the Magnolia Avenue corridor area “immediately and significantly decreased as a result,” authorities said.

“This wasn’t a one-and-done operation, and our enforcement efforts will continue until our community members, businesses, and visitors feel a constant sense of safety in Riverside,” said Larry V. Gonzalez, Riverside Police Chief.

“The Riverside Police Department will continue its directed enforcement and efforts to investigate those engaged in the trafficking and sale of illicit drugs within our neighborhoods, amongst other crimes affecting the safety of community members,” the police department said.
